I'm surprised you say that. To flip this on its head, what would be your principled argument to accept ambient surveillance?

I don't doubt that license plate readers are used primarily to solve crimes. But the fact that it is collected and can be made available to anyone essentially strips you of privacy in everyday life. Cops are people too; once the tech is available, it is sometimes abused to spy on spouses, neighbors, journalists critical of the local PD, and so on.

There is also a more general argument: an ever-growing range of human activities is surveilled to root out crime, and we can probably agree that the end state of that would be dystopian: it'd be a place where your every word or even every thought is proactively monitored and flagged for wrongthink. We're ways off, but with every decade, we're getting closer. I'm not saying that Flock-listening-to-conversations is the line we can't cross, but if not this, then what?
